demorse is a morse code to text decoder application for Linux. It
detects the "dihs" and "dahs" that make a morse code character
via the computers sound card, which can be connected to a radio
receiver tuned to a CW transmission or to a tone generator. Demorse
is currently a non-interactive tool, and decoded morse code signals
are sent to stdout.
